Abstract: In order to reduce the noise in the readout signal, the invention provides an image pickup apparatus comprising a pixel including a photoelectric conversion unit for converting the incident light and accumulating a resulting electrical signal, and a transfer switch reading the electrical signal accumulated in the photoelectric conversion unit or a signal based on such electrical signal, and potential control means for maintaining the potential of the signal line higher than that of the photoelectric conversion unit while the photoelectric conversion unit accumulates the electrical signal.

Abstract: A photoelectric conversion device having a substrate, a light reception area formed on a surface of the substrate, the light reception area having at least one unit pixel, an insulating layer formed on the substrate including the light reception area, and a light shielding group made of a plurality of light shieldings and formed through the insulating layer along a direction perpendicular to the substrate, the light shielding group surrounding the light reception area.

Abstract: There is provided an image pickup apparatus comprising a plurality of pixels each including a photoelectric conversion unit which converts incident light into an electrical signal and accumulates the electrical signal, an amplifier transistor which amplifies and outputs the signal from the photoelectric conversion unit, a transfer transistor which transfers the electrical signal accumulated in the photoelectric conversion unit to the amplifier transistor, and a processing transistor which performs predetermined processing, and a control circuit which sets the signal level supplied to the control electrode of the transfer transistor in order to turn off the transfer transistor to be lower than the signal level supplied to the control electrode of the processing transistor in order to turn off the processing transistor.
